Title: Machine for caring for floors such as a floor cleaning machine and such as especially a carpet cleaning machine
Inventor: STEIN THOMAS
IPC: A47L9/04
Filed: 1996-02-15
Abstract: To adjust a brush roller to the current operating conditions, a brush attachment to hold the brush roller and drive mechanism is realized in the form of an upper part and a separate inner part.      The inner part is thereby mounted in the upper part so that the inner part can pivot by means of an axle, and the brush roller is pressed against the surface to be cleaned by means of a spring element. The inner part has a suction chamber for the brush roller, and has a rear floor strip, preferably of convex curvature, in the vicinity of the axle to create a seal. The front area is sealed by means of a floor strip on the brush attachment.

Title: Method of and apparatus for controlling a process
Inventor: BAILEY GRAHAM
IPC: G05B21/02
Filed: 1996-05-03
Abstract: The present invention relates to a method of controlling an output variable of a process having long dead times and delay times, for example for controlling the interior temperature of an abosrber refrigerator, and also relates to an apparatus for carrying out such a method. The output variable of the process, such as the interior temperature, is sampled and compared with a desired value in order to determine a desired value deviation. In dependence on the determined desired value deviation, a manipulated variable, such as the power supplied to the absorber, is calculated in such a manner that the output variable of the process is brought near to the desired value. After the lapse of a waiting time, a value of the manipulated variable is newly determined. During the waiting time, the manipulated variable is not altered.  The waiting time is calculated on the basis of the difference between the value of the manipulated variable and an earlier value of the manipulated variable. A  controller for carrying out the method comprises a memory for an earlier calculated manipulated variable and a timer which is designed to receive the earlier calculated value of the manipulated variable and the current value of the manipulated variable, to calculate a waiting time from these and, after the lapse of this waiting time, to start a new calculation of a value for the manipulated variable.

Title: Telecommunications system and method of telecommunication
Inventor: QUELCH PETER J
IPC: H01Q9/04
Filed: 1996-07-10
Abstract: Telecommunications system in which an outside antenna is positioned to direct radio signals in a divergent beam towards a predetermined wall surface area of a building.  The outside antenna is sufficiently close to the building to require constancy of the radio signals to noise ratio of radio signals transmitted by the outside antenna.  The signals transmitted at the building are received by patch antennas located on the wall surface area (e.g. in practice upon windows) for connection of the outside antenna to individual terminal outlets in the building.  These terminal outlets are preferably connected by cable to the patch antennas, but the terminal outlets may be radio receivers.

IPC: A21C15/02
Filed: 1996-08-30
Abstract: Baked waffles, especially breakfast waffles, are brought to the market for commercial sale in unfrozen condition, being packaged in sealed aseptic packages. The waffles are prepared by being baked to an extent less than 100% and greater than about 80% baked, and at least until the temperature of the interior of the waffle being baked has reached at least 72°C. The waffles are removed from their waffle form and transferred to a packaging station while still hot, and are placed into heat stable package that is sealed while each baked waffle remains at an elevated temperature, thereby rendering the package aseptic. The sealed aseptic packages are cooled and stored so that the baked waffles arrive for commercial sale in unfrozen condition. The baked waffles, in their sealed aseptic packages, may have a shelf-life of up to three months. Conveniently, the baked waffles are prepared in an apparatus which comprises two chains of opposed waffle iron forms which pass through an oven for baking. The chain runs formed by a plurality of opposed waffle irons are positioned so that the waffle irons are closed and opened due to the geometry of the chain runs, whereby loading and unloading each respective waffle iron is easily effected. Generally, a heated discharge conveyor zone is located at the exit end of the oven so that the temperature of the baked waffles remains at an elevated temperature throughout the period of time following its baking and until it is placed into the packaging. This renders the package aseptic; and after sealing the aseptic package, it is taken for subsequent cooling and handling into the commercial market. Thus, the baked waffles are brought to the market unfrozen, in sealed aseptic packages.

Un petit réservoir sans fond (20) est placé dans le réservoir régulier (12) d'un cabinet de toilette de façon à créer deux réservoirs distincts dont l'un à l'intérieur de l'autre. A la base (27) de ce petit réservoir se situe une ouverture (26) permettant l'entrée d'eau à partir de la base du réservoir régulier. Sur le dessus du petit réservoir est situé un clapet (24) contrôlé par le même bras de levier (18) que celui de la chasse d'eau du cabinet de toilette et qui se referme dès qu'on relâche ce bras de levier. Quand le petit réservoir est plein et que son clapet est fermé, si on active le bras de levier (18) de la chasse d'eau du cabinet pendant un temps suffisant pour ouvrir le clapet du réservoir régulier, le petit réservoir reste plein d'eau pendant que le réservoir régulier se vide. Ce système permet une économie automatique de la quantité d'eau du petit réservoir, lors de l'utilisation du cabinet de toilette.

Title: Machine-readable label
Inventor: BARNS-GRAHAM MICHAEL DAVID
IPC: G06K7/015
Filed: 1996-03-18
Abstract: A label (100) for identification purposes, has a compact matrix of machine-readable cells (101-109) holding information and including the BCH error-correcting code. The cells may be binary, ternary (grey levels) or have more levels and may use colours. These labels are both easily detectable and accurately readable, because a plurality may occur within a single complex image captured outdoors, where adverse lighting and contaminants may detract from ideal conditions. Accordingly some (usually 4) characteristic cells (101, 102, 103, 104) per label are reserved for use as locators which, when found, indicate position, orientation and values on the scale of grey levels used in the symbol. A grey or white label perimeter may be used to determine intra-label lighting variations, as described in relation to the disclosed reading steps. One or more portable digital camera captures images and relays them to an analysis and decoding machine.
